DRYING APPARATUS FOR FEAT AND THE LIKE.

Specification of Letters Patent.

Patented May MP, 1910.

Application filed August 13, 1909. Serial No. 512,631.

To all-whom it may concern:

Be it known that I, CHARLES ALBERT MATHESON, of Perth, in the county ofLanark, Province of Ontario, Canada, have invented certain new anduseful Improvements in Drying Apparatus for Peat and the Like, of whichthe following is a specification.

My invention relates to improvements in drying apparatus for dryingsubstances such as peat, and the objects of my invention are to providean auxiliary apparatus to be used in connection with any of the ordinaryforms of driers which drive a certain quantity of moisture from the peatin the form of steam, further objects being to make the apparatus cheapand simple in con struction and such that the quantity of moisturedriven from the peat may be regulated as desired; and it consistsessentially of a pan or receptacle substantially in the form of a seriesof steps, said pan being suspended from a suitable frame work by chains,rods or other swinging suspension, a steam box located beneath the pan,steam inlets and outlets, and suitable peat feeding attachments andsupporting frame; the various parts being constructed and arranged indetail, so far as the invention has at present been completed, ashereinafter more particularly described.

In the drawings, Figure 1 is a longitudinal section of my apparatus.Fig. 2 is a transverse section on the line X-X, Fig. 1.

In the drawings, like letters of reference indicate corresponding partsin each figure.

It may first be explained that the peat on leaving the driers of theclass described is only partially dried and contains a large amount ofsteam which if the peat is left in piles will gradually be condensedinto water and will remain as such in the mass of peat.

The particular object of this invention, is therefore, to stir up thepeat when it comes out of the ordinary drier and at the same time keepit warm, thereby preventing the condensation of the steam and giving itaccess to the air to enable it to pass off. With this end in view, Ihave constructed the device as shown, and in which A is a suitableframework consisting of longitudinal base pieces a, sloping longitudinalupper beams a, cross pieces a and transverse base pieces a the upper andlower portions of the frame being suitably connected by the uprights a.

B is the pan into which the peat to be further dried is fed, preferablyfrom the trough H. This pan consists of a series of steps b, the objectof which is to continuously force the peat forward and prevent itspiling up in one place in its descent. The pan in its general directionslopes from inlet to outlet. Side walls I) are provided to prevent thepeat from falling from the sides in its descent.

Below the steps b is located a steam box C, the upper portion of whichis formed by the bottom of the pan and the lower portion is formed by asheet of galvanized iron or other suitable material 0. A layer ofasbestos or other heat non-conducting ma-' terial c is located beneaththe steam box and to the sides thereof, and the whole box is containedin an outer casing D, preferably made of wood or like material. Thestep, box, pan and easing are provided with cross-pieces cl extendingunderneath the wooden outside casing and chains E extend from thecross-pieces a of the frame to the cross-pieces cl, thereby suspendingthe pan and steam box.

F is a steam inlet and G is a steam outlet for the box.

Suitable means are provided for oscillating the suspended portions in abackward and forward direction, such as the crank 2' on the shaft I,connected to the pan B by a link 2". The result will be that the peat asit falls on the pan will gradually work down to the bottom falling offthe lower end as shown. At the same time steam from the exit of theboiler is passed into the steam box by the inlet F, escaping through theoutlet G and the peat will consequently be kept at a'temperaturesufficiently high to prevent the steam from condensing and the continualmotion and shaking up of the peat will enable the steam which has beenformed and held therein to escape into the air and the result will bethat the percentage of moisture contained by the peat when it has passedthrough the machine, will be greatly reduced.

What I claim as my invention is '1. A peat drier comprising a suspendedcasing and a removable pan therein formed with a series of steps overwhich the peat is adapted to pass, and means for heating the pan andmeans for reciprocating the casing.

2. A peat drier comprising a suspended to the cross bar, and a removablepan in the casing and a removable pan therein formed with a series ofsteps over which the peat is adapted to pass, means for heating the pan,means for reciprocating the casing,

and a layer of heat insulating material between the pan and the casing.

3. A peat drier comprising a casing formed on the bottom with aplurality of transverse crossbars, a frame work flexible membersextending through the frame work casing over which the peat is adaptedto pass, means for heating the pan and means for reciprocating thecasing.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.

CHARLES ALBERT MATHESON.
